I can imagine this being initially an accidental discovery like oh every time so and so’s body interacts with the WiFi signal it’s the same pattern… until someone starts exploring this further… and then some engineer or their manager started looking for applications for this. In my experience engineering researchers especially are very good with coming up with use cases for whatever tech they’re working with, with little ethical consideration.
The moment we use the NIMBY label we prejudice ourselves against potentially legitimate local and global concerns and specific local protest movements. I do that too on some issues but do wonder sometimes whether I’m being unfair. I guess the determining factors would be how big a sacrifice a local community is asked to make, how great the greater good that sacrifice will serve, also who is protesting and what arguments they bring forth, what values they stand for, how these values align with yours, etc.
